It is not about generic shell problem, it is about specific behavior that
on Windows Python already uses cmd.exe shell hardcoded in its sources. So
for crossplatform behavior on Windows, it should escape symbols on command
passed to cmd.exe that are special to this shell to avoid breaking Python
scripts. What you propose is a bad workaround, because it assumes that all
Python users who use subprocess to execute hg or git should possess apriori
knowledge about default subprocess behaviour with default shell on Windows
and implement workaround for that.
